MARTIN- L. KEYES, OF OARTHAGE, NEW YORK, ASSIGNOR TO FRANKLIN E.ROBINSON, OF SAME PLACE.

BU RIAL-CASE.

SPECIFICATION forming part of Letters Patent No. 655,560, dated August'7, 1900.

Application filed December 5,1899l Serial No. 739,321. (No model.)

To a/ZZ whom, it may concern.:

Be it known thatl, MARTIN L. KEYES, a citizen of the United States ofAmerica, and a resident of Carthage, Jefferson county, New York, haveinvented certain new and useful Improvements in Burial-Oase Machines, ofwhich the following is a specification.

My invention relates to mechanism for turning a burial-case made fromwood-pulp; and it consists in the mechanism hereinafter more fullypointed out and claimed.

The object of my invention is to furnish a mechanism for taking aburial-case as the same comes from the dies in a hydraulic press andproperly supporting the top and vbottom and turning the same from itsreverse position to its normal position, where the same can be safelytransported to the ovens for evaporating and solidifying the fiber.

In the drawings, Figure 1 is a perspective view of my machine. Fig. 2 isa front view of the same, broken lines in both instances indicatingparts removed. Fig. 3 is an end view of Figs. 1 and 2, taken from theleft side of said figures. Fig. 4 is an end view of Fig. 1, taken fromthe left, showing the burial-case in its normal position. Fig. 5 is avertical section showing the relative position of the parts. Fig. 6represents details of construction of the locking mechanism for holdingthe mechanism in the position illustrated in Figs. l, 2, and 3. Fig. 7is a side view of the fol-l lower and the cam, brokenlines indicatingparts removed. Fig. 8 illustrates a section of the hydraulic press, themale portion of the die in the hydraulic plate being shown incross-section and the hydraulic piston being shown in full lines, themovable portion of the device being shown in full lines to the right ofthe standard of the hydraulic press. Fig. 9 is the same view as Fig. 8,dotted lines indicating the position of the inverted burialcase. Fig. 10illustrates a left-hand view of Fig. S, and Fig. l1 is a verticalsection of Fig. 9 on line A B.

In the drawings similar characters refer to corresponding parts in theseveral views.

In the drawings, arepresents a portion of the frame of a hydraulicpress, in which I make the body portion of burial-cases from wood-pulp.

a', Figs. 8 and 9, represents the perforated male die, mounted on platea2, Figs. 8 and 9, supported and operated on hydraulic pistonTheperforated male die a works inside of the female die. (Not shown inthe press.) Both dies are vperforated for permitting the outflowy of thewater Huid in the pulp. The two portions of die are brought into propersituation with reference to each other, and 6o the liquid pulp is placedbetween the dies under hydraulic pressure untilsufficient pulp is placedbetween the dies for making the required thickness, When the hydraulicpressure is applied and the fibrous portions of the pulp are compressedinto the requisite shape approximately and into any thickness. Stripper2, having spurs or projections 2 on its upL per surface, is placed overor around the male die a and rests on flange a, so that the edge of 7othe case is built in engagement with the spurs, the spurs or projectionsbeing embedded in the edge of the wall of the case, thereby pre;ventingthe case from moving, slipping, or sliding when the male die iswithdrawn and the case is prepared to be moved out of the press. Vhenthe male die is lowered out of the case in the operation of thehydraulic press, the stripper engages lugs or supports on the frame,which are not shown, and the male 8o die is withdrawn, leaving thestripper and the case thereon in position to be moved out of the pressinto the position Where it rests pre paratory to having itsposition'inverted, as hereinafter more `particularly pointed out.

The operations here enumerated are the ordinary operations of a pulphydraulic press, and the parts illustrated will be readily understood,as they are not particularly claimed in this patent, but are simplypartially illusgo trated to more fully understand the purposes andoperations of the mechanisms, which I will now proceed to more fullydescribe.

The wood-pulp burial-case 1, formed in the hydraulic press, I place atthe point where 95 the edges of the inverted burial-case rest atstripper 2, which consists in a frame constructed, preferably, of ironor steel'a'nd provided on its upper surface with a series of engagingpoints 2, Fig. l1. It should be borne roo in mind that the rib or ribscan be used inside of the projecting points over or against which snsvis run on antifriction-rollers 2b.

the inverted edge of the burial-case rests for from tipping or otherwisedisarranging the preventing sliding or slipping when the burial-case isremoved from the press to be transported to the drying-room. Thisstripper 2 (Hest illustrated in Figs. S and 9.) Theseantifrictionrollers are mounted in the press and are provided tofacilitate the moving of the stripper and the burial-case out of thepress and on frame 13, hereinafter more particularly pointed out. Thisstripper is used to free the wood pulp case from the male die, whichmoves into the -position shown in Figs. S and 9, leaving the burial-caseon the stripper, so that it can be moved into the position shown indotted lines in Fig. 9 for the purpose of turning the same off from thestripper into the-position shown in Fig. 4. Vhen this is accomplished,the stripper is swung back into the position shown in Fig. 8, where itcan again be used. After the burial case is formed and the strippercontaining the case is brought into the position shown in Figs. 1, 2,and 3 it is important to turn the burial-case from its inverted positionto the reverse position (shownin Fig. 4) while it is in the green state,and to prevent the burial-case from slipping on the stripper while thereversing operation takes place it is important to hold the same, andfor this purpose I employ points 21L on the stripper, Fig.'11; but a ribor ribs may be used in place of the points. In order to hold the case onthe stripper while it is being reversed, I provide a wood rack or frame3, made of slats, and place the same on the inverted bottom of the case.The slats in this rack are run lengthwise of the case and supportcross-slats 4. (Best illustrated in Figs. 4 and 5.) This rack supportsthe case when it is transported to and through the dry-room. Afterplacing the slatted rack on the inverted bottom of the case as it restson the stripper I then place over the rack follow-blocks 5 at each end.These follow-blocks are held to the slatted rack by loop 6, which slipsover the end of the follow-block and in which is mounted cams 7, Fig. 7,pivoted at 8, so arranged that the upper surface of the cam will swingagainst stop 8a. The lower end ofthe cam engages spring 9, secured tothe bolster-plate, so that by turning handle 10 of cam 7 downward itbears on the spring, which also acts on the follow-block through theoperation of connecting-rod 11 11, having hooked end 12, the lower endof which hook clamps over stripper 2, so that the upper and lowersurfaces of the case are clamped between two surfaces during the processof reversing the case or holding the same from buckling or collapsing.The purpose of this arrangement is to prepare the case for reversing anddelivering the same into the dry-kiln. The stripper 2, carrying 'theinverted case, is drawn on the rollers from the press onto frame 13,fixed to bracket 14, by sliding the same in groove 14L (illustrated inFig. 11) to prevent the stripper burial-case and is held in the invertedposition by pin 14, Fig. 8, in the frame, which secures the samealinernent for the movement of the strippers as the antifriction-rollsin the press, so that the stripper can be drawn out in the samehorizontal line. The frame portion 13 is held in this position by notch14, Fig. S, as hereinafter more particularly pointed out. Brackets 14are pivoted at l5 on standards 1G, mounted rigidly on rod 17. Rod 17 issupported in supports and carries counterbalance-weight 18,which swingsbelow the floor in order to assist in counterbalancing the weight of thestripper and burial-case when the same are swung into the position shownin Fig. 4, the counterbalancing-weight being shown only in Fig. 4. Thismovement is accomplished by spring-catch 19, having notches 20, thecatch being moved out of engagement with catch 19, Fig. 6, in whichposition the parts are held vertically, the notch 20inthe spring-catchbeing provided to engage a stop on the stripper preparatory to swingingthe case and stripper when the stripper and case are freed from thepress into their reverse position. Vhen the catch in the spring is movedout of contact with the stop, the stripper and case are then swung onthe bearing into the reverse position. (Best illustrated in Fig. 4.) Thestripper is moved in suitable ways in the frame, preferably onantifrictionrolls 2b, as best illustrated in Fig. 8, and the ways in theframe in which the stripper moves horizontally are best illustrated inFig. 11 at 14a. By drawing the stripper and the inverted case mountedthereon horizontally out of the frame, the stripper moving in suitableways to permit its motion when it reaches the proper distance, itsfurther movement is arrested by a notch in the spring-catch engaging thestop, and the same is held stationary until the operator can steady theswinging motion, when the catch is elevated out of contact with the stopand IOC IIO

the case and stripper are swung into the reverse position, (shown inFig. 4,) where the case is deposited on supports from the door, where itis ready to be transported to the drykiln, and the swinging mechanism isready to have the stripper removed and the case transported to thedry-kiln and the stripper returned to the press for a repetition of use.The burial-case in its reversed operation is steadied by the operatorholding and steadying the handle 21, Fig. 1, during the movement ofreversing the burial-case, finally resting on supporting-blocks A A onthe door, the counterbalancing-weights below the floor assisting theoperator in reversing the `position of the case.
